  • the film-conveying device 4 comprises means 6 for taking a film from the magazing 5, capable of moving, in a movement associated with that of the mould parts 2 and 3, in a second direction Y, Y' at right angles to the first direction X, X' between the position of taking and the position of deposit.
  • the moulding machine 1 comprises a device 7 for conveying a moulded object between a position of taking the object between the male and female mould parts 2 and 3 (with mould in open position) and a position of evacuation of the object.
  • the object conveying device 7 comprises means 8 for removing the object from the mould capable of moving, in a movement associated with that of the mould parts 2 and 3, in the second direction Y, Y' at right angles to the first direction, between the position of taking and position of evacuation.
  • the film-conveying device 4 and the moulded object conveying device 7 are capable of moving in synchronism so that, when the film-conveying device 4 is in position of deposit of the film between the mould parts 2 and 3, the object-conveying device 7 is in position of taking the object between the mould parts 2 and 3 and, when the film-conveying device 4 is in position of taking a film from the magazine 5, the moulded object conveying device 7 is in position of evacuation of the object.
  • the film-conveying device 4 and the object-conveying device 7, and in particular, the film-taking means 6 and the object-taking means 8, are mounted on the same support 9, via which they are driven by a system of two intersecting racks 10 and 11 meshing with each other.
  • One of said racks, 10, parallel to the first direction X, X' is fast with a mould part (the male mould part 2 in the example shown) via a support 12, and the other, 11, parallel to the second direction Y, Y' and mobile parallel to said second direction Y, Y', being slidable on a support 13 fast with the female mould part 3 via a guide 14, is fast with the support 9 bearing the film-conveying device 4 and the object-conveying device 7.
  • the film-taking means 6 are associated with a linear stroke jack 15 adapted to displace them in the first direction X, X' so as to be able to deposit the film exactly at the bottom of the mould.
  • the means 8 for taking the object are associated with a linear stroke jack 16 adapted to displace them in the first direction X, X' to bring them exactly in contact with the object on the male part 2 of the mould, as well as with a rotary jack 17 for pivoting them about an axis 18 perpendicular to the plane defined by the first (X, X') and second (Y, Y') directions.
  • a first object stacking system (FIGS. 3c and 3d) is arranged so as to be opposite the object-taking means 8 with jack 17 in pivoted position.
  • the film-taking means 6 and the object-taking means 8 comprise depression nozzle 20 and possibly suction cups 21 (FIG. 2).
  • the magazine 5 is associated with a drive jack 22 adapted to animate the magazine in a reciprocating movement parallel to the first direction X, X', so as to bring the end film contained in the magazine 5 into contact with the film-taking means 6.
  • the film-conveying device 4 and the object-conveying device 7 comprise ejectors 23 for ejecting either the film or the object, adapted to slide in bushes 24.
  • the initial step (FIG. 3a) is considered as being the one during which the means 6 for taking a film 30 deposit the latter at the bottom of the cavity of the female mould part 3 (where it is taken up by depression means which have not been shown), and this by displacing means 6 with the aid of jack 15 in direction X, X', whilst the means 8 for taking the object which has just been moulded (not visible in FIG. 3a in order to render the drawing clearer) and which is borne by the male mould part 2 seizing the object, being displaced against part 2 with the aid of jack 16.
  • the film-taking means 6 are then withdrawn from the cavity of the female mould part 3 with the aid of jack 15, whilst the object-taking means 8 are disengaged from the male mould part 2 with the aid of the jack 16 (position in broken lines in FIG. 3b), taking object 31 along by depression, after which the means 8 are pivoted about axis 18 with the aid of the rotary jack 17.
  • the rack system 10 and 11 makes it possible to drive (in direction Y, Y') the film-conveying device 4 into position of taking opposite magazine 5 and, at the same time, the object-conveying device 7 into position of evacuation opposite the system 19 for stacking moulded objects. Simultaneously, the mould 2, 3 closes.
  • the jack 22 makes it possible to drive magazine 5 in the direction X, X', against the film-taking means 6, whilst the actuation of jack 16 makes it possible to introduce the object 31 which has just been moulded into the stacking system where it is maintained by appropriate means after the objects moulded previously.
  • the end film 30 which is contained therein may be seized by said means 6 and maintained thereagainst by depression, whilst the jack 22 returns the magazine 5 to its position of FIG. 3c (FIG. 3e). At the same time, the jack 16 returns the object-taking means 8 in their retracted position.
  • the device 4 for conveying the film 30 is driven by the system of racks 10 and 11 into position of deposit opposite the cavity of the female mould part 3, whilst the object-conveying device 7 is taken in the vicinity of the male mould part 2, position in which the actuation of the rotary jack 17 will make it possible to bring the object-taking means 8 opposite part 2, then, by actuation of jack 16, against the object which has just been moulded, whilst the mould was closed.
  • the jack 15 takes the means 6 with the film which is maintained therein to the bottom of the cavity of the female mould part 3. The cycle therefore terminates by a return to the initial step illustrated in FIG. 3a, followed immediately by another identical cycle of manufacture of a moulded object.
